OpenAI is expanding plugin integration with new extensions that surface as native apps in ChatGPT, appearing in the sidebar, within conversation panels, and as file viewers to enhance how plugins interact with the interface, with Canva cited as a sidebar app example.

These extensions enable full native app experiences inside ChatGPT, including content selection from plugins and richer input forms, driven by the Composer features.

A new MCP 2.0 standard is required for MCP-triggered events to function, and plugins must support this specification to enable automations.

ChatGPT plugins can now react to MCP events via signed webhooks, with defined usage limits governing plugin interactions.

OpenAI’s DevDay showcased ongoing enhancements to plugins, notably support for event-driven automation and broader automation capabilities.

Developers can use Plugin Creator to build or update plugins, with redesigned submission flow and improved ranking to surface relevant plugins in directories and conversations.

Availability notes indicate extensions are generally available, but web-based extensions aren’t yet live for Free and Go plans; these users will gain access via the browser later.

OpenAI is expanding plugin integration, security, and discovery while enforcing rollout constraints to balance safety and usability.

Related coverage notes workspaces with admin controls and visitor consent, clarifying distinctions among local plugins, public listings, and recommendations for discovery and review.

Additional updates include Plugin Creator improvements, clearer submission feedback, new discovery ranking, and extensions introducing sidebar apps and file viewers with rollout limits for some plans.

MCP events let plugins trigger automations in ChatGPT when monitored events occur in connected apps, enabling automatic actions such as task creation or document changes.

The ecosystem connects to over 4,000 apps with shared plugin permissions across ChatGPT variants and related products, managed through the Plugins tab.
